- /*
- * INET An implementation of the TCP/IP protocol suite for the LINUX
- * operating system. INET is implemented using the BSD Socket
- * interface as the means of communication with the user level.
- *
- * Holds initial configuration information for devices.
- *
- * Version: @(#)Space.c 1.0.7 08/12/93
- *
- * Authors: Ross Biro, <bir7@leland.Stanford.Edu>
- * Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
- * Donald J. Becker, <becker@scyld.com>
- *
- * Changelog:
- * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
- * - fix sbni: s/device/net_device/
- * Paul Gortmaker (06/98):
- * - sort probes in a sane way, make sure all (safe) probes
- * get run once & failed autoprobes don't autoprobe again.
- *
- * FIXME:
- * Phase out placeholder dev entries put in the linked list
- * here in favour of drivers using init_etherdev(NULL, ...)
- * combined with a single find_all_devs() function (for 2.3)
